Serious Speaker Issues systemwide, even WORSE in Logic!

[DasCubano]

wondering if anyone else is encountering my problem. i'm having some serious issues with these monitors i finally got (M-Audio Studiophile AV-40s). it almost sounds like they're cracked when listening to iTunes or when receiving input from my system in general (SL 10.6.7 on a standard MBP 5,5 and when I load up Logic and play anything whether hitting play on the transport bar or playing my AKAI MPK25 thru ANY vst at all, it goes from bad to AWFUL—as in indiscernible crackling and noise, no matter how low i turn the volume on the monitors, or via any control on the system or in logic! the only thing that lets me know that it isn't the monitors is that i have my Roland MC-505 also running into the monitors via a 1/4" cable. i can turn each part as loud as possible and the monitors themselves and everything is fine. just louder, as it should be. same thing when i don't use the monitors at all, the speakers in the MacBook Pro produce the sound you would expect to hear from a given vst or sample. i have no idea what this could be from.

 

i'm at my wits' end here. i've even installed the virtually useless app Hear, which did absolutely nothing. in fact even the simple effects in it like thereverb and simulated acoustics, etc—none of it does anything. very strange. if anyone has any ideas or has come across this problem before i'd appreciate any insight/help you might have. some additional info about my setup below.

 

okay so my macbook pro has a USB audio-out dongle called an MD-PORT AN1 with a 1/8" jack going from it (with a volume dial halfway down the cord—from an older speakers set i used before) and into the front of the AV-40s on the other end via another 1/8" jack. 2 USB MIDI controllers (all USB connections are through a 4way hub) which i'm STILL trying to figure out how to assign to different tracks/software instruments to play different parts live, simultaneously. The monitors are connected to one another via some regular wire like most stereo-grade speakers. there's a 4channel Nady® mixer taking 2 mics and another out from my MC-505 (all 1/4" jacks) all into the MacBook Pro through a 1/4" jack adapted down to 1/8" to fit in with that port set to receive signal rather than send it out. so when a track is armed in Logic i can hear signal from the drum machine, mics or anything else going into my little Nady 4ch mixr. still nothing stands out that i can think of being the cause for this kind of faulty output coming ONLY from my Mac. as i mentioned the signal from my MC-505 goes straight into the Studiophiles and come out clean. PLEASE HELP! I gotta get these tunes/melodies/beats laid out while i'm still inspired! thanks.

forgive the darkness. but u can basically see all the essential parts.

1. If your audio interface requires drivers, go to the website and download the latest version. Make sure it is compatible with the OS you're using.

 

(1a. If there is no version of the drivers explicitly compatible with the OS you're using, THROW AWAY THE INTERFACE - as any company that hasn't managed to put out drivers after a year and a half obviously doesn't want your business.)

 

 

2. Open Audio-MIDI Setup Utility, open the audio devices window, select your audio interface in the pane at the left, and change "clock" to something other than it is now, and then back to "44.100 Hz, 24-bit", and clock source to "internal".

well i'm not using an interface per se. there's the little Nady 4ch mixer i'm running the mic & groovebox through and into my audio port on the side of the MBP. the little MIDI>USB converter, but all that does is act as a MIDI PCI card would PLUS it's not even part of the problem with the static-y awfulness. still no idea why my monitors are responding that way! as before, any insight/advice/2¢/etc.… it's all welcomed!!!

Either I'm missing something, or you need to make up your mind.

okay, I was listening to a little Alice in Chains in iTunes at my abuelita's house when my usual experience was spotted with static like my Logic problem. to be fair, Logic was open however that sound wasn't coming through Logic so I don't know exactly what the culprit can be said to be. i'm looking into adjusting stuff in the Audio MIDI Setup utility. Wish me luck, all.
